PAPER BOTTLE AND THE LIKE.

Specification of Letters .Patent.

Application filed July 17, 1913. Serial No. 779,477.

Patented Aug.18,1914.

To all whom it may concern Be it known that I, WILBUR L.'WRIGHT, acitizen of the United States,- residing at Washington, in the Districtof Columbia, have invented certain new and useful Improvements in PaperBottles and the like, of which theiollowing is a specificatiom Thisiirvention relates ,to certain improve- I ments in paper bottles, andthe like; and the invention.

objects and nature of the invention will be readily understood by thoseskilled in the art in the light of the following explanation of theaccompanying drawings illustrating' what I now believe to be thepreferred embodiment from among other formations within the spirit andscope of the An object of the invention is to provide a paperbottle orother receptacle havin its paper wall at its upper end or neck outwardlyor bell shaped by the application flared of a neck ring thereto, so thatthe neck ring rests in the bell mouth and is upheld thereby.

The invention consists in certain novel' features in construction and incombinatlons and arrangements as more fully and particularly set forthand pointed out here inafter.

Referring to the accompanying drawings:-Figure 1, is a sectional view ofthe neck or mouth portion of a paper bottle or vessel showing the neckring resting thereon preparatory to being forced down to bell the mouthof the aper vessel and secured.- Fig. 2, is a sectional view of themouth or i neck of the vessel after the neck ring has been forced downtherein and secured thereto.

In the drawings, I show a paper bottle or other vessel wherein thesurrounding upright or longitudinal paper wall 1, tapers or contractsupwardly from a com aratively large base to a comparatively sma l neckor mouth, producing a bottle approximately frusto-conical in form, withthe paper wall terminating in the top edge 2.

In carrying out my invention, I provide a metal (or other suitable stiffmaterial) annulus or neck ring or vertically arranged sleeve 3, havingitslower edge bent or turned inwardly to form an approximatelyhorizontal annular inwardly or radially projecting flange 4, extendinginto and Surrounding the open center or'bore of the ring. The upper.portionr-of the ring flares or bells upwardly and outwardly andterminates in an exterior dependin annular flange 5, so that the upperportion of the ring is in the form of an invdrted U. The lower endportion of the ring is approximately cylindrical and is of an externaldiameter to permit said lower end of the ring to freely sli down intothe mouth of the paper wall 0 the bottle about to the position disclosedby Fig. 1, of the drawings. After the ring has been placed in the mouthof the paper wall to the position ap roximately as shown in Fig. 1, asuitably s ped plunger or presser head descends on the ring and forcesthe same downwardly a certain distance with respect to the paper wallapproximately to the position shown by Fig. 2. The ring-islongitudinally or vertically formed to flare or hell the mouth or neckof the paper wall outwardly when forced down therein. Thedownwardanovement of the ring in the paper wall under heavy 3 pressure,forces the neck or'top edge of said wall to follow the outwardly curvingupper portion of the ring, and thereby expands, outwardly curlsoiyfiares said portion of the wall outwardly with the rim to the form orposition indicated by 7, an

so that the outer annular edge portion thereof is approximately curledby and within the ring. The bottle canbe then rapidly rotated against asuitable spinning tool or other imp ement to spin tuck or turn theexterior depending free edge of the ring inwardly below and with thecurled top edge 1 portion 7 of the paper Wall and thereby securely lockthe ring in the bottle mouth. The flange at the lower end of the ringand located within the bottle mouth, forms a sealing seat for the disksor caps generally employed as closures for milk bottles and machines.The mouths of t e bottles must be strong'enough to withstand thevertical devices of the thrust of the closure disk-tor'cing plungers,without breaking or bending down or otherwise distorting. ll accomplishthis desirable result by employing the flaring neck rings with themouths of the paper walls of the bottles beiled outwardly therein andthereby stiiiened and rendered capable of resisting excessive downwardpressure on the rings. The neck ring rests on and in the bell of thepaper wall and hence an exceedingly strong durable structure is producedenabling the paper bottles to he successfully employed in filling andcapping machinery.

It is evident that various changes, variations and modifications mightbe resorted to without departingltrom the spirit and scope of myinvention, and hence I do not wish to limit myself to the exactdisclosures hereof.

What I claim is 1. A paper wall receptacle having its mouth portionformed by a neck ring having an internal closure-se'at-torming shoulder,said ring having a closure-retaining cylindrical portion above saidshoulder and flaring upwardly and outwardly above said cylindricalportion and from thence extending outwardly, downwardly and inwardly toform the top edge or the bottle mouth and a projecting exterior runaround said mouth,

said ring fitting down within the paper wall of the receptacle, theupper end of said paper wall bodily flaring and curling-outwardly withinsaid projecting exterior rim, the lower exterior edge of the ringprojecting inwardly below said curled portion of said wall to lock thering on the wall.

2. A bottle having a paper material wall, and a neck ring extending downtherein and forming the bottle mouth, said ring forming a sealing-diskshoulderand flaring upwardly above said shoulder and curving upwardly,outwardly and downwardly to form said mouth with'a curved top edge and aprojecting exterior rim, the upper end of said wall belling and curlingoutwardly and downwardly within said curved top and rim of said ring tosupport said ring against collapse of said wall under capping andfilling machine pressure on the ring andits shoulder, the exteriorannular edge or said ring extending inwardly below said curled end ofsaid wall to lock the ring thereon.

In testimony whereof ll afix my signature in presence of two witnesses.
